I have a 220 gallon fowlr . last few days I noticed my emperor angel is flashing and has cloudy eyes and cloydy fins or fraid fins . The eye has somethings protruding I believe its flukes. I added prazipro to my DT and watched for few minutes to my surprise the white stuffs began falling out and the emperor eyes has some white stuffs hanging . Is there anything I need to do besides prazi? Also how long to treat .. any Sid effects of prazipro treatment in DT?
